IMO, that sort of depends on WTF() does. One case where a bare except
is well used is when stdandard output/error are not going anywhere
useful and you want to log the exception and then terminate:
try:
whatever()
except Exception as e:
syslog("foobar: terminating due to unhandled exception %s.\n" % e)
sys.exit(1)
Alternatively, if you're not at the top level in the call tree,
sometimes it's useful to log an exception but still pass it on up in
case somebody higher up wants to handle it:
def asdf():
try:
whatever()
except Exception as e:
syslog("Function asdf() terminating due to exception %s.\n" % e)
raise
